Oil Filter Lid

[curand]

Changed the oil on my 996 Mk2 GT3 this weekend. When removing the oil filter lid, the filter and the plastic part inside the filter, did not come out with the lid itself, but stayed in the filter housing. When I put it back again, I put the plastic part and the new filter in the housing, before I screwed the lid back on. I now understand that the plastic part inside the filter should be attached to the lid, isn't that so? Are they snapped together? Guess I have to remove everything again, to see if I can get the lid correctly assembled or if it´s broken, buy a new one. Did anyone else have the same experience?

Hi Curand... The plastic stanchion that goes through the middle of the filter element does snap into the lid before reassembly. The filter element often stays in the filter body when unscrewing the lid. My process is to get all the parts out on the bench in a pan for cleaning and then discard the old filter element. You will find a small pool of oil left inside the filter body on the engine. you may or may not want to get that oil out with a turkey baster.....I don't bother myself. Clean up the lid, plastic stanchion on the bench and then replace the TWO o-rings. One is on the lid above the threads and you usually get a new one with your new filter element. The second o-ring is on the small end of the stanchion. It's less than a centimeter across. It is Porsche part number 999 707 465 40. They are stupid expensive from Porsche and you may be able to duplicate them from another metric o-ring source. I've been known to reuse them when I'm out of new ones. For reassembly push the new filter into the filter body on the engine first. Snap the stanchion with the small o-ring into the lid, then spear the lid-stanchion through the upward end of the filter. It should feel 'bottomed' just about when the threads of the lid meet the filter body. Then start the threads and feel it all push together inside as you tighten the lid to 19 lbs ft.

OK, good. Now I know how it should be put together. Yes, I replaced the small o-ring as well. I'll take the lid off and put it together correctly.
